I tried again and removed the Nvidia-Drivers with

sudo emerge -C x11-drivers/nvidia-drivers

and installed

sudo emerge x11-drivers/xf86-video-nouveau

this works with Kernel 5.7.0!

~> inxi -G
Graphics:  Device-1: NVIDIA GP107 driver: N/A
           Display: server: X.Org 1.20.5 driver: nouveau,vesa
unloaded: modesetting resolution: 1680x1050~N/A
           OpenGL: renderer: Rasterizer v: 2.1 Mesa 19.1.4

but now xrandr no longer works.

~> xrandr -q

Screen 0: minimum 1680 x 1050, current 1680 x 1050, maximum 1680 x 1050
default connected 1680x1050+0+0 0mm x 0mm
   1680x1050      0.00*
